HTTP Debugger Features

Debug HTTP API calls to back-ends and between back-ends

Debug HTTP API calls

HTTP Debugger is a proxy-less HTTP sniffer with clean UI and very easy to use. Doesn't change the browser's configuration for the proxy. Can display HTTP(s) traffic from any browser and JAVA/.NET apps.

Edit and Resubmit HTTP Sessions

Edit and resubmit tweaked HTTP sessions back to your server and check how it handles such requests, for example: testing the security or authorization flow with or without special headers, cookies, etc.

Highlighting of Errors and Slow Requests

HTTP Debugger automatically highlights errors, slow and large requests. You can create custom highlighting rules in one click.

Visualize Your Traffic

Visualize your traffic in form of charts. Find the slowest and largest requests, most requested domains and content types.

Modify HTTP Traffic On-Fly

With HTTP Debugger you can emulate various server behaviors without actually making required code changes on the server side. You can add/remove HTTP headers, change HTTP content, redirect requests from one server to another, and many more.

Debug Issues Remotely

Your clients may use the HTTP Debugger FREE Express version to record HTTP traffic locally and send you session files containing the reproduction flow of a problem.

See Incoming HTTP Traffic of Local Servers

With HTTP Debugger you can view the incoming HTTP traffic for locally running web servers, powered by Node.js, IIS Express, Apache and others.
